My thoughts in here, gets kinda scientific but here’s what I make out of time travel: If you go back in time and change something, that’s going to cause a ripple in the threads of time which is going to cause a paradox. To elaborate, if you went back and changed something, then why did you even go back? As in, if you change the past, the present as you know it will be ripped off and therefore you will have a different future all together. Okay, I’m just ranting now. Have a good day!
